Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wet rock core is directly dried to measure salt crystal mass, then the measurement process is simple, but the measured mass includes both salt crystals and evaporated saline water, leading to significant error
Solution Approach 1:
The invention segments the measurement process into two separate measurements: first measuring the mass of the wet rock core, then after drying, measuring the mass of dried rock core and separately measuring the mass of dried saline solution. This segmentation allows distinguishing between salt crystal mass and evaporated water mass, resolving the contradiction between simple process and accurate measurement.
Solution Approach 2:
The invention uses an intermediary substance (alcohol) to wash and extract the salt crystals from the dried rock core. The alcohol dissolves the salt crystals and carries them away, allowing separate measurement of salt crystal mass independent of the rock core mass. This intermediary approach enables precise measurement while maintaining operational simplicity.
2Ease of operation
If the mass difference between wet and dry rock core is used as salt crystal mass, then the calculation is straightforward, but the result is too large due to inclusion of evaporated saline water mass
Solution Approach 1:
The invention segments the total mass loss into two components: mass loss from rock core drying and mass loss from saline solution evaporation. By separately measuring and calculating these components, the invention enables straightforward calculation while achieving accurate salt crystal mass determination, resolving the contradiction between ease of operation and measurement precision.
Solution Approach 2:
The invention uses feedback by measuring the mass of saline solution before and after evaporation, and using this information to correct the salt crystal mass calculation. The measured data feeds back into the calculation process to eliminate the error caused by including evaporated water mass, achieving both straightforward operation and accurate results.
